Kristin Cavallari's #TBT Is a Fun Trip Down Memory Lane — PHOTO

Do you remember Teen People? That seminal magazine that celebrated all things celebrity, style, and the late 1990s and early 2000s? If so, hen Kristin Cavallari's Throwback Thursday photo on Instagram will totally delight you. In fact, it's pretty great no matter what — she's so young! This is before the height of her fame — she's 17 — and it's her first photo shoot ever.

Since then, so much has changed for Cavallari. She has grown up to be a mother of two — she recently gave birth to her second baby, Jaxon Wyatt. Is this the girl from Laguna Beach? Time flies when you're binge watching other shows, I guess.
